ABSTRACT
he purpose of this study was to assess the efficacy of thethermoplastic filling techniques, Touch’n Heat®, TC®System andTagger’s Hybrid Technique, in oval-shaped canals at the apicalthird.Thirty-three human uniradicular lower pre-molar teeth weretreated by the reciprocating movement technique and weresubsequently split into 3 groups, according to the filling techniqueperformedTouch’n Heat (TH), TC System (TC) and the Tagger’sHybrid Technique (TG).In the sequence, the teeth were sectionedat 2mm and 4mm from the foramen and images were taken tomeasure the percentage of canal area filled with the obturationmaterials as well as void spaces.Data were submitted for Kruskal-Wallis statistical analysis. Irrespective of levels, data showed thatthe TC System delivered the best results.(p<0,001).At 2mm and4mm levels, there was no difference between the TG techniqueand the TH technique (p<0,001).With all the techniques and atall levels, no differences were observed regarding the void areavariable.(p>0,001).The techniques evaluated showed anadequate filling with obturation materials and the TC has reachedthe highest filling with the guta-percha material.
RESUMO
O objetivo desse trabalho foi avaliar a eficiência de preen -chimento das técnicas termoplásticas Touch’nHeat®, SistemaTC®e Híbrida de Tagger em canais de anatomia oval no terçoapical. Trinta e três dentes pré-molares inferiores humanosunirradiculares foram instrumentados pela técnica do movimentoreciprocante e posteriormente separados em 3 grupos segundo atécnica de obturação Touch’nHeat, Sistema TC e Híbrida deTagger. Em sequência os dentes foram seccionados nos niveis de2 mm e 4 mm a partir do forame e imagens foram capturadaspara mensurar a porcentagem da area do canal preenchida comos materiais obturadores e os espaços vazios. Os dados foramtabulados e submetidos ao teste estatistico de Kruskal-Wallis.Independente dos níveis, os dados mostraram que a TCapresentou os melhores resultados. (p<0,001). Nos níveis de 2 e4mm não houve diferença entre as técnicas TG e TH (p<0,001).Em todas as técnicas e níveis não foram observadas diferençascom relação a variável áreas vazias. (p>0,001). As técnicasavaliadas demonstraram um adequado preenchimento pelosmateriais obturadores, com destaque para o preenchimentosuperior com guta-percha pela técnica TC.
